Well, I might as well do the disclaimer at least once. I don't own Adventure Time, nor do I own the gender bent version :'C If I did, it would be FioLee everywhere! Hope you enjoy, read on :D

Fionna sat on the couch in the main room playing B-Ma. Again and again the little ball kept getting past her panel. Eventually she threw her controller to the side and growled in frustration. "Ugg, B-Ma, your cheating!" she said crossing her arms and leaning back.

B-Ma giggled and paused the game. "No, you just stink at this game." Her face appeared on the screen and she smiled her digital smile. Fionna shook her head, "No, you were definitely cheating." She looked around the house.

"Hey, where's Cake? Shouldn't she be up by now?" B-Ma gave Fionna a look, "Don't you remember? Cake said she was going over to Lord M's house to spend the evening with him." Fionna blinked a few times, thinking it over. "Oh, oh yeah, I remember now."

She sighed, sliding further off the couch. "Uggg, Cake spends all of her time with LM these days. It's starting to bug up our adventuring." Her stomach growled, making her jump. And it's messing up my meal time too she thought with a frown.

Getting up, Fionna went into the kitchen, pocking her nose in almost every cabinet and drawer until she found a can of soup. "We need more food," she thought out loud after examining the expiration date on the label.

Pouring the contents out into a bowl, Fionna popped the soup into the microwave. After eating a warm and slightly weird tasting meal, she decided to go to the Candy Kingdom for some groceries. She wrote a short note down that simply read: Out for food. Be back soon, and was out the door before long.

It did her some good, being out of the Tree House for a little while. It had been forever since she had been anywhere, especially the Candy Kingdom. Wonder how Gumball is doing she thought to herself. The last time they had talked, it had been about a possible mission for her and Cake.

But that had been a week ago, and if Gumball hadn't called yet, then he must not have needed the two adventurer's help after all. Fionna sighed. She had been let down lately at how Gumball didn't need her around anymore.

Usually he didn't take notice of her there, but now it seemed he didn't even take notice of her not being there. It was just sad that the guy she had had a crush on for at least four years running hasn't got a clue about it. She had tried being patient, and wait for him to come around, but she wasn't really good at waiting.

Once she had even tried to come clean to him about how she felt, but had failed miserably, only making a fool of herself and causing him to be even more clueless than before. Fionna mentally face palmed herself at the memory.

She was awakened from her pondering state by the Candy Kingdom gate. Wow, that was a short walk. After saying hi to the banana guards, Fionna continued through the main streets of the Candy Kingdom. All the stores and stands were in the Central Plaza. She waved at some bypassing candy people, and helped a couple citizens with reaching, rolling, and carrying assorted items on the way.

Eventually she made it to the Plaza. Fionna idly walked into and out of candy shop after candy shop, buying the essentials and a little extra for herself.

Something that caught her eye in Goodies Glamour was a silver necklace with a heart shaped locket in the middle. Fionna sat there admiring it through the window glass. She even made daydreams about how she would walk into the castle and charm Prince Gumball with it around her neck.

"Oh Fionna," he would say," What a fool I have been! How did I not notice you?"

"Oh, I don't know. But do you notice now?" Fionna would say gently touching the locket like one of his royal lady friends.

"Of course I do! It's been you I have loved this whole time, and now that I have realized it, will you kiss me?

"Oh, I don't know. But why not?"

A hand tapped Fionna on the shoulder as she leaned in to kiss her imaginary Gumball. Opening her eyes she realized quite quickly that the actual Prince Gumball was standing in front of her, a quizzical look on his pink face.

"Uh Fionna, what are you doing?" He asked tilting his head to the side. That cute little look in his eyes, the slight smile on his plush face. It was enough to make her melt on the inside, and ironically her legs gave a little. Fionna felt her face heat up and knew that it must have been as red as an apple by now.

"Uhhhhhhh, uhhmmmm I-I… Hey," she said pathetically. All of a sudden the bags of groceries slipped from Fionna's grasp. She yelped as they spilled oranges, strawberries, and assorted meats and chesses.

Gumball coward away from the avalanche of food as it came raining down on him. He caught an apple or two, but the rest hit the ground. Fionna fell to the sugary pavement, a mad blush on her cheeks.

"Sorry, I am so sorry Gumball! I don't know what happened; I just lost my balance there for a minute…" She babbled frantically pulling cabbages and a carton of milk into her arms and then dumping them into a now empty bag.

She heard a laugh off to the side. Looking over she saw a chuckling Gumball, his eyes squinted almost shut from mirth. "That's quite alright Fionna. I haven't seen something this funny sense you tricked the Ice Queen into kissing Cakes butt."

He wiped an imaginary tear from his eye, and then kneeled down to help pick up the scattered food. Fionna watched, paralyzed. She hadn't heard Gumball laugh in so long; it was almost tempting to drop something else just to hear it a second time.

Turning back to her work Fionna, with the help of Prince Gumball, picked up all the foodstuffs fairly quickly. She stuffed the last tomato in one of the less full bags while Gumball squeezed a bunch of bananas in between the oranges and grapes.

Wiping the thin film of sweat from his face, the candy prince turned to Fionna with a smile, "That didn't take long." She blushed a little and nodded, "It's 'cause you helped and junk. Thanks, you didn't have to you know."

Prince Gumball waved a hand, "It was nothing. Plus I was looking for you anyways. Chance meeting you here, huh?" He walked up closer to her. She could smell his bubble gum scent and it sent her through the roof. She just wanted to go up and breathe him in, put her nose in his chest and just smell.

Fionna pushed the thought away, feeling embarrassed, as if he could see what she was thinking. Reaching into his coat pocket, he pulled out an envelope. There was a very official wax seal on it in the shape of one of the gumball guardians. Prince Gumball handed it to her.

"What's this?" Fionna asked not wanting to disturb the perfect looking seal. Gumball smiled, looking very proud. "It's you and Cakes invitation to my very sweet sixteen." Fionna looked at him, her mouth a jar slightly.

"You're turning sixteen? Wow, your old," she said. Gumball frowned a little, "I am not old. I am still very young. This is the coming of age, were an old child becomes a young adult." He went back to his smug happy look.

Fionna smiled back at him. "So, you're inviting me?" Gumball gave her a dumbfounded look, "Well of course..."

Maybe he has noticed my absence…

"…and Cake too. I need some top security there to keep any uninvited guests out…"

And we're back to unnoticeable.

Fionna felt her spirits dampen. He just wanted her there for security, nothing more. She gave a heavy sigh. Prince Gumball didn't even notice. He just kept on talking about who was going and who wasn't, decorations, what she was to wear, what time to show up.

Fionna bent down and picked up all of her bags. Prince Gumball at least noticed that. "Huh? Fionna, I haven't finished telling you about the Cinnamon Toast Brothers. They are the best classical music players in all of Aaa."

She looked back at Gumball. He was frowning slightly; probably mad at her incompetent listening skills. She didn't even try to forge up a fake smile. "Me and Cake will come by tomorrow, you can talk then."

Prince Gumball put his hands on his hips, "Well ok. But come early, there is a lot to prepare for." And without so much as a glance back, he turned and walked away down the candy street. Fionna lowered her gaze, and trekked on down the street in the opposite direction, bags in tow.

After bypassing through the gate again, Fionna found it increasingly harder to keep the tears at bay. Not here, not now. Wait until you're in the Tree House, then you can…, "Cry." Fionna felt a single tear fall from her closed eye.

"Awww is my little bunny crying over that spill in central?" a mocking voice said out of nowhere. Fionna dropped all her bags for a second time. Turning around, and wiping the tear quickly away, she faced the source of the voice.

Marshall Lee floated a few feet away, just within arm's reach. His face held a smirk, while his hands held an umbrella. He wore his usual jeans and plaid red shirt, and a big rimmed sun hat sat upon his head.

"Marshall, you stalker!" she growled. The vampire laughed and rose out of harm's way as Fionna tried over and over to grab his foot and pull him down. "Ya know, 'hi' would be nice sometimes."

She continued to jump, but to no avail. He laughed, and stuck his tongue out at her. This only made her madder. "Marshall, how did you know about that?" He leisurely laid back in midair, crossing his legs in the process.

"Oh, ya know. I was just passing through the Candy Kingdom, doing the usual, scaring babies, tripping old ladies, when I caught sight of your little performance in front of Mr. Gummy bear. Way to go, by the way. Anyways, just wanted to see what you were up to, but instead I find you crying." He smirked down at her.

Fionna glared at him. "I wasn't crying," she said plainly. Marshall Lee's smile widened, "Yes you were my little adventuress. Fionna, the great and powerful, actually cries! Amazing!" He did a small bow, and tipped his wide brimmed sun hat up a little.

Fionna looked away, embarrassed, "Shut up Marshall."

The Vampire King looked down at her, a playful smile only making her feel worse. "But Fifi, we must celebrate this momentous occasion! You have finally showed you do have tear ducts…"

"I said shut up!" She yelled. Flopping onto the ground, Fionna pulled her bunny hat over her face, and pulled her backpack so that it sat on the top of her head. All she saw was darkness, and all she could think about was Gumball.

She didn't hear anything, and for a while she thought that Marshall had lost interest and gone. But then she felt something cold grab her hand that held down the hat. Gently, Marshall Lee guided it up until Fionna's tear soaked face was uncovered.

She hadn't even noticed her body shacking from the sobs or even the wetness from the tears. The only thing she felt was the pain for Gumball's mistreatment and Marshall Lee's cold hand on hers.

"Fionna, why are you crying," she heard him ask. She took a shuttering breath. She didn't have to tell him anything. She could talk to Cake about Gumball, but not Marshall Lee! He was a vampire, a teenager, and worse of all a boy. He wouldn't understand.

"Fionna, please, just tell me why you are crying." Fionna almost laughed. Was that concern in his voice? Compassion, maybe even worry? As if he was capable of those emotions. She tried to pull her hat back down, but he wouldn't let her.

"Fi, talk to me."

Fionna thought it over. He is my friend, I could tell him. No.

"Fi, please…"

Yes.

"I'm sorry I made fun of you…"

No.

"…please, just tell me why you are so upset."

Yes. Yes, she could trust him. She hoped.

Fionna sighed deeply. "I'm crazy to tell you this…" she mumbled.

He leaned in closer, "What?" She shook her head, "Nothing." Marshall Lee sat patiently, watching her like a hawk. Fionna finally looked up enough to get a good look at him.

He wasn't smiling anymore, and he didn't look like he was about to laugh. Maybe he was being serious. Maybe…

"Ok, ok I'll tell you." Fionna looked at the ground as she said this. "It's… I mean, I-I'm having trouble with… It's Gumball." She said quickly, as if it all made sense. Marshall Lee raised an eyebrow "Gumwad? What about him?"

She wiped a hand across her eyes. "I-I like him… but, I don't think he likes me that way back. He doesn't even notice if I'm there or not, and he invited me to, to the sweet party were me and Cake and him, and stand guard, and Cinnamon Toast Brothers, and…"

Marshall Lee looked overwhelmed, "Wait, hold up Fi. I have no idea what you're talking about. Slow it down." He gave her a confused smile, but this only made her cry more.

"Don't you get it? How don't you get it! Ugggg, you are just as clueless as Gumball. What is up with guys, huh? Are you just born stupid, or what? I like Gumball, but he doesn't like me back! Ok, I said it, happy?"

Fionna buried her head in her arms, and continued crying, waiting for the laughing, or the jokes about what a stupid thing that is to cry about, or even that he was going to go tell Prince Gumball himself.

But instead the exact opposite transpired. Letting go of her hand, Marshall grabbed her chin and pulled her head up until she was facing him once more.

His umbrella blocked out the sun, and created a cool shade in which they were now. His face was, for once, solemn. No probing smirk, no smart remarks about how she looked while crying. Just a warm look in his eyes that said, 'I know exactly how you feel.'

This made Fionna even more confused. How would he know how she felt? And how come he was acting like he understood, like he cared. He was probably just messing around with her emotions again. But what if he wasn't?

This thought took Fionna by surprise. Marshall Lee the Vampire King actually cared about Fionna, the Human. It was just too plain weird to think about. Of course they were friends, but they were crash-a-party, prank-a-monster friends. Not talk-about-our-feelings-and-actually-give-a-crap friends.

Marshall raised an eyebrow and did his little smirk were only one fang stuck out. "Fionna, don't cry over that gumwad, he isn't worth it." He pierced her eyes with his cold black ones, tinged with red. She waited for him to continue, but that was all he said. He looked like he wanted to say more, but he just shook his head, and floated back a little.

"All this cry babyness is going to destroy your adventuring spirit. Geez, suck it up Fio. Can't believe you even got me to be all mushy, yuck…" He said, reverting back to his brash bad boy attitude.

Fionna wiped the last of her salty tears away, a slight smile coming through the gloom of her frown. "Whatever. Dude, you were all serious for once in your immortal lifetime. I've never seen that side of you."

Marshall Lee looked distractedly at something she couldn't see, "That's because there is no other side of me. I'm the Vampire King, awesome bass player, and hated by all." He wiggled his eyebrows at Fionna.

Despite herself, she laughed. She stood up and repositioned her hat, tucking stray pieces of hair back in. Her backpack slid back down to its according place, and she straightened out her shirt.

Dusting off her skirt, Fionna started to pick up the groceries once again that day. I really need to remember to wash these fruits and vegetables when I get home. Marshall helped pick up some of it, but usually just floated idly by, watching her.

She felt very uncomfortable with his eyes boring into the back of her head. Fionna eventually turned to look at him, and when their eyes met, he quickly turned his head. Weird she thought. After packing the last bag, she picked them all up into her arms.

Marshall Lee floated over and took two from her, holding them with his free hand. "I can at least help you carry this load to the tree fort. Besides, I wanna see if you start crying again." He gave her a devilish grin.

She frowned up at him. "Drop it," she said sternly. She didn't want to talk about Him anymore, and she sure as heck didn't want to hear Marshall talk about it. He picked up on her mood right away. "Kay Fifi. Whatever will make you feel better," he floated up above her slightly.

It was a quick and quiet walk back to the Tree House, and as soon as they passed through the door Fionna threw the groceries on the table and collapsed on the couch with a groan. Marshall Lee soon followed suit, and floated just above the couch cushion beside her.

"Hey, where's the fur ball?" Marshall asked looking around the messy Tree House. Fionna shrugged her shoulders and said,

"She went over to Lord M's house to spend the day with him, so I have the whole place to myself." She glanced over at Marshall, noticing a bored expression on his face.

"You wanna play some video games? We just got a new one called Grave Diggers" she offered, gesturing to B-Ma across the room. He just shook his head. "Naaa, I'll just go home. This sunlight and heat is making me roast if not fry. Besides, you'll probably want some time to be alone."

He looked over at her, almost as if daring her to suggest something else. But it was true, she did need some time alone to sort out what had happened today. She nodded and smiled up at him.

"Yeah, ok. And thanks man, for helping me." Fionna blushed slightly. Marshall smirked and started to float over to the door. "I will carry bags for you any day, my little bunny." She blew her bangs out of the way, "You know what I mean dude."

"I'm not sure that I do" he said perplexed, but she knew he was just trying to keep his bad boy attitude up. She shook her head, he would probably never be that nice to her ever again, but who knows, maybe he would.

The door shut as Marshall Lee left, and once again Fionna was alone. Maybe she would take her own advice and play some Grave Diggers, but taking a closer look, Fionna realized that B-Ma was charging.

"Dangit," she said. Then she remembered the envelope. Reaching into her backpack, she pulled it out and broke the wax seal without any hesitation. She unfolded the three way folded papers to find a very neat and tidy hand writing, of course Gumball's.

She began reading.

To Fionna the Human and Cake the Cat,

Greetings, this is Prince B. Gumball of the Candy Kingdom, announcing that you are formally invited to Prince B. Gumball's Sweet Sixteen Ball.

Please wear ball room dressings and such shoes.

Thank You.

It was short, and offered no other direction except to come dressed in ball room attire. No wonder he needs me and Cake to come over to explain, there is nothing written on the invitation. Fionna shuffled the papers and found two tickets lined with a golden lace looking design.

The last paper revealed what activities and foods were going to be there, including a detailed description of the Cinnamon Toast Brothers, who were to play there. Fionna read through some of it, but got a little hungry after reading about the cupcakes, pastries, and puddings that were to line the tables at the Ball.

Setting the contents of the envelope down on the table, Fionna got up and put away the groceries, but left out a few apples, grapes and bananas to make a fruit salad with. Afterwards, she took her sword and cut them up skillfully into a bowl.

When the bowl was empty of all fruit, she polished her sword about a hundred times. Then she washed her clothes, wiped down her shoes, and made her bed of animal pelts. And even after all that, she was still bored.

The truth of the matter was that she was trying to get her mind off of Gumball and Marshall Lee. After their encounter together, Fionna felt like there was something about the vampire that had just been off lately. But her real distractions were of the Prince, and how ignorant of her he was being.

After doing almost the entire kitchen, Fionna started on the dishes. She almost cut herself with a knife, but managed everything rather nicely. While putting up the last glass, she heard the door open and close.

Turning her head, she saw her sister walk in with her viola. "I'm baaaack!" she said loudly. Fionna quickly shut the cabinet door and ran over to hug Cake and welcome her home. "Oh, it's good to be back in my own house. So how was your day girl?"

Fionna shifted from one foot to the other. "It was alright, I guess." Cake looked at her and then saw what she had been up to.

"Why, Fionna! The whole house, it's so clean. You even did the kitchen." She cast a worried glace at Fionna, "And what have you been thinking about to make you do all this work?"

Fionna felt a blush coming on. She recounted her day's activities to Cake, even the parts with her crying. They were best buds, and Cake didn't judge. But when Fionna talked about Marshall Lee's performance, she brushed it off as not real.

"Fionna, honey, he's a vampire. And on top of that, this is Marshall we're talking about. He's just jacking up you heart guts, and messin' with your head. He isn't as good as you think." Cake snorted and shook her head, paws on her hips.

"I swear he messes with everyone, but you the most. It's unfair I tell ya." Fionna patted Cake on the head "Ok, ok enough. Marshall isn't so bad, and besides, he could be worse." Cake crossed her arms with a humph, but didn't say anything else.

Fionna was about to ask her how her day with Lord M. had gone, when Cake all of a sudden asked, "So where is the invitation?" Fionna pointed over her shoulder at the table. "It's not much, just a bunch of stuff about food and music. We have to dress up in, well, dresses."

Cake smiled "Oh, Fionna! I'm going to make you such a pretty dress. Every girl there is going to envy you, and every guy will want you, wink wink." She winked when she said it. Fionna just looked down at her feline friend, and smiled sadly.

"Yeah, every guy except Gumball." Cake frowned. "Oh baby girl, don't be so sad. This is a big event, one were you could meet a lot of new princes, might even make a few new friends. Wouldn't that be nice?"

Cake looked up at Fionna with big kitten eyes. She walked up and grabbed Fionna's skirt, holding it like a little kid would when begging his or her mother for a piece of candy. She really wanted to go to this party, and even more so to make Fionna a dress.

Fionna sighed. "Yeah, that would be nice, I guess." Cake jumped up, her tail all fluffed. "Then it's settled! Candy Kingdom, here we come! But, eh, when is it again?" Fionna walked over to the table and scanned the text.

"Says its tomorrow, at 6 p.m., ends about midnight. Wonder if we'll see Marshall there." Fionna looked up to see a very unhappy expression on Cakes face. "It would be best if he stayed home. If he even gets near you, I will make him pay for making fun of your crying."

Fionna blushed, not wanting to think about it. Cake noticed the dull red, and quickly changed the subject. "Anyways, let's talk about your dress. What color do you like?"

Fionna waved her hand in the air, a nonchalant look on her face. "I don't wanna talk about all that frilly girl stuff. Just make it the way you want, I couldn't care less."

Cake was ecstatic. Then she turned serious, and pointing a finger at Fionna, she said, "I do not want this dress torn to ribbons like the last one. I don't care if Ice Queen herself is about to capture Gumball, it stays just a fresh as a daisy."

Fionna held her hands up in defeat and muttered under her breath, "It was Ice Queen the last time…," then smiled and nodded her head. Cake gave a satisfied grunt. "Good."

Cake went into their shared bedroom, and began working on the dress. "If I'm going to make the best dang dress I've ever made before tomorrow, I had better start working," she had said.

Fionna was a little disappointed. She had hoped that the two could stay up and talk, maybe watch a movie, pop some popcorn.

But she understood Cake's drive for perfection, so she just let it go. They would be able to have fun some other time. Having nothing else of value to do, Fionna awoke B-Ma, who had finally finished charging, and ended her day just as she had started it. Getting her butt kicked at Pixel Paddle.

Hope you liked it. Please review, and give me constructive criticism, I need to know if it's bad or good. I will post the second chapter soon, so don't worry, I will update. Thanx for reading XD Sry, but in this FioLee, Gumwad is sixteen. I know he is supposed to be eighteen, but in this one, he is sixteen. (This little mistake was noticed by my little sister, so thank u Cienna.)
